Patent ES-424327-A1 (ES)
Title: Thread supply device for textile machines
IPC: B65H51/22
Filed: 1974-03-15
Abstract: A thread supply device for a textile machine, comprises a thread drum upon which the thread can be wound tangentially and a thread control element which can be moved into two positions, the thread being axially unwound at a speed independent of the winding speed in the first position (intermittent thread supply) and the unwinding speed being limited to the winding speed in the second position (positive thread supply). A switch is actuatable by the thread control element for continuously actuating the winding drive in the case of positive thread supply. During intermittent thread supplying, a sensing element monitors the thread storage located on the thread drum and disconnects the winding drive when a maximum amount of thread has been attained on the thread drum. The switch is constructed as an electrical double-throw switch which assumes a first switching position during intermittent thread supply and a second switching position during positive thread supply. The sensing element is switched into a route by means of the double-throw switch during positive thread supply such that a control circuit of the machine drive of the textile machine, which circuit is connected to said route, is caused to de-energize the machine drive when the thread storage on the thread drum exceeds a maximum value and/or falls below a minimum value.

Patent ES-449189-A1 (ES)
Title: Method and machine for rolling threads or the like
IPC: B21H3/04
Filed: 1976-06-15
Abstract: Round blanks consisting of ductile metallic material are formed with threads, knurled or otherwise profiled in a rolling machine wherein a head supports two or more cylindrical dies each having a flat and a profile including a first section of gradually increasing radius, a second section of constant radius and a third section of gradually decreasing radius. The head may rotate about a non-rotating blank so that the dies orbit about the blank, or the blank may rotate about its axis with respect to a stationary head. The flats of the dies face the periphery of the blank when the head is moved to operative position by the slide of a machine tool, and the dies are thereupon caused to turn so as to move the first sections of their profiles into frictional engagement with the blank. The rolling operation is completed when each of the dies completes a single revolution. The rotary movements of dies are synchronized by a gear train whose gears can lock the dies in selected angular positions so that the flats face a blank during movement of the head to or from the operative position. The gears can be unlocked in automatic response to movement of the head to operative position and are relocked as soon as the dies complete a single revolution.

Patent ES-8102356-A1 (ES)
Title: X-ray powder diffractometer.
IPC: G01N23/207
Filed: 1980-01-30
Abstract: A computer controlled asymmetric texture-sensitive parafocussing X-ray powder diffractometer employs an incremental rotating specimen holder for azimuthal rotation through an angle DIAMETER . The specimen holder is rotatable through an angle alpha from a symmetric position in which the specimen surface normal makes an angle (90- theta ) DEG with both the source-to-specimen and detector-to-specimen directions. In order to maintain the Brentano focussing condition, the detector is supported on a slide which can be moved towards and away from the specimen by a stepper-motor drive. A ratio K of the detector-to-specimen distance R on the one hand and the X-ray source-to-specimen distance P on the other hand is constrained to a range c < K < f. The desired focussing condition is realized by computer control which maintains K = sin ( theta + alpha )/sin( theta - alpha ) and modifies the measured value of the intensity by multiplying it by 0.5 (K + 1) K<0.75>exp [ mu R(K - 1)], where mu is the linear absorption coefficient for air.

Patent ES-8404200-A1 (ES)
Title: A nozzle reactor and method of use thereof in atomising and mixing fluid reactants.
IPC: B01F5/04
Filed: 1982-12-23
Abstract: A spray mixing nozzle and a method for reacting an acidic fluid and a basic fluid by using the spray mixing nozzle. The nozzle includes a central channel, at least one intermediate annular channel surrounding said central channel, an outer annular channel and a mixing chamber having a generally cylindrical upper section, a generally conically-shaped lower section and an axially aligned discharge orifice. The acidic fluid and the basic fluid are directed through the central channel and the intermediate annular channel into the upper section of the mixing chamber at relatively low velocities and a pressurized gas is simultaneously directed through the outer annular channel into the upper section of the mixing channel at a relatively high velocity. The high velocity gas acts to strip apart and at least partially atomize the acidic fluid stream and the basic fluid stream in the upper section of the mixing chamber. The gas and the partially atomized fluids are then subjected to a high degree of turbulence in the lower section of the mixing chamber and thereby substantially completely atomize and mix the fluids. The mixed and atomized fluids then begin to react and form a powdery or highly viscous paste product which is discharged from the discharge orifice.
